| 摘 要： | 根据视觉暂留原理,设计了一种线阵LED图文显示系统。选用TI公司的MSP430G2553单片机为主控制器,用直流电机带动线阵LED电路板高速旋转,经过不同位置时,点亮相应的LED,在旋转平面上显示静态或动态图文信息,通过光敏元件感应外界光照强度控制LED灯亮暗程度。该系统具有成本低、驱动简单、视角广、耗能低等优点。

| Abstract: | The theory of vision hysteresis is analyzed,and a chart and article display system of linear LED is designed.The hardware parts adopt the MSP430G2553 as the main control chip.The linear LED circuit board is rotated by the driven of the DC motor in a high speed,and the relevant diodes are lightened in different positions,then the chart and article information of Static or dynamic is displayed in rotating plane.In addition,the lighteness of LED is controlled by photosensitive element.The system has the advantages of low cost,simple drive,wide viewing angle,and low consume. |
